Method for breeding gall-inducing harmful insects

Abstract

The invention discloses a method for breeding gall-inducing harmful insects. The method comprises the steps as follows: placing fresh branches, roots, stems or fruits with insect galls acquired in the field into a sealed plastic bag; before placing, disinfecting the plastic bag by potassium permanganate, and placing the insect galls of the leaves into a papery closed container; placing the sealed plastic bag or the papery closed container into an artificial climate box, controlling the breeding environment temperature to be 25-1 DEG C, the humidity to be 60-70% and the illumination time to be 12 h, and opening the box in the morning and closing the box in the evening each day; and controlling the breeding density to be 80-100 insects / m<3>, and checking the number of the gall-inducing insects every 6-7 days. According to the method, the gall-inducing rate of the gall-inducing harmful insects is increased in a short time by controlling the temperature and the humidity, reducing the space of the breeding container and properly reducing the space activity range of the gall-inducing harmful insects, so that sample materials are provided for determining the species, biology, ecology as well as physiology and biochemistry of the gall-inducing harmful insects and a basis is laid for prevention and control of the gall-inducing harmful insects.

Description

technical field [0001] The invention belongs to the technical field of feeding gall-causing insects, in particular to a method for feeding gall-causing pests which is simple, high in galling rate, short in time and low in cost. Background technique [0002] Galls are a very common biological phenomenon in nature. Galls are abnormal tissues with diverse shapes and complex structures produced by gall-forming organisms that lay eggs on the surface tissue of the host and induce accelerated cell division of the host plant. Extremely adverse effects, leading to the death of host plants in severe cases. For example, Dryocosmus kuriphilus, a major quarantine pest, belongs to this group; at the same time, galls of various shapes condense the significant, complex and close relationship between insects and plants, and are the best model materials for exploring the co-evolution among multiple species. Gall-causing biology is also a new direction of ecological research. Among all gall...

Problems solved by technology

In the subsequent breeding process, it was found that the water absorption of the carton was strong, which caused the host plant to lose water and the branches to dry up, making it difficult for gall insects to produce galls.
